From the Publishers
This September issue of The Application Notebook should be reaching our audience just as the busiest time of the year ramps up in the world of spectroscopy.
They say that timing is everything, and though this saying may have originally been applied to Broadway and Vaudeville in the early twentieth century, it is just as true when it comes to the field of modern-day materials analysis. For this September issue of The Application Notebook should be reaching our audience of analytical chemists, lab managers, and other industry professionals just as the busiest time of the year ramps up in the world of spectroscopy.

The coming months will see a spate of conferences and symposia taking place in locations from Reno, Nevada, to Philadelphia, Pennsylvania, to just about everywhere in between. And this year, for the first time, you can add Spectroscopy to the list of publications and organizations who will be hosting such an event. "The Spectroscopy Summit" will be taking place in early November in Boston, Massachusetts, and we are looking forward to presenting attendees with one of the most informative, dynamic events of the season. Held in conjunction with SPIE and utilizing their formidable and extensive conference-organization resources, this event will certainly attract the best and brightest in the field of materials analysis. Please check either the Spectroscopy website (

In the meantime, we would also like to take this opportunity to introduce the newest member of our sales team, Stephanie Shaffer. Stephanie has many years of experience in this field and will be a great asset to Spectroscopy and LCGC. Her contact information can be found in the masthead along with our own, and we encourage you to contact any one of us with any questions you might have. Information about submitting materials for the February 2009 edition of this series can be found on page 35, and as always, please enjoy the issue.

Top articles include an examination of the current trends propelling atomic spectroscopy forward and post-conference coverage of the 2026 SciX show in Sparks, Nevada.
In this Q&A, we recap the October edition of “What’s Nu,” which covered topics such as how novel spectroscopic and analytical methods are transforming environmental monitoring, medical treatment, and accessibility in scientific research.
In this Q&A article, we highlight several prominent researchers being recognized at the 2026 SciX Conference for their significant contributions to spectroscopy and photonics and discuss what these researchers talked about at the conference.
Amy Colleran, a Postdoctoral Researcher in the Centre of Metabolomics Research at the University of Liverpool, is exploring how to detect volatile organic compounds by bubbling them directly into colloidal silver and gold nanoparticles.
The Eastern Analytical Symposium returns to Plainsboro, New Jersey, November 16–18, with a keynote on AI-ready data and a posthumous award honoring solid-state NMR researcher Robert Schurko.
In this segment of our SciX interview with Kevin Wilkinson, a professor of environmental chemistry at the Université de Montréal, discusses extending lead isotope work to greater distances and explains why graduate students need adaptability, critical judgment, and coding skills more than expertise in any single instrument.
Atomic spectroscopy has quietly gone from counting elements in bulk to counting single nanoparticles, imaging tissue at the micrometer scale, and reading Martian rocks from several meters away. The instruments got smaller, the software got smarter, and the questions they can now answer got a lot more interesting.
